A student neutralized 16.4 milliliters of HCl by adding 12.7 milliliters of 0.620 M KOH. What was the molarity of the HCl acid?(1) 0.168 M (3) 0.620 M
(2) 0.480 M (4) 0.801 M

Answers

Answer 1

Answer:

The molarity of the HCl acid is 0.480 M. The correct option is 2.

What is molarity?

Molarity is the division of the mass of the solution to the volume of the solution.

The formula that is used is

$\rm M_1V_1= M_1V_2$

Putting the values in the equation

0.620 * 12.7 = M1 * 16.4 = 0.480

Thus, the molarity of the HCl acid is 2). 0.480 M.

Answer 2

Answer:

Molarity is equal to the moles of solute over liters of solvent. In getting the molarity of HCl, you must know the formula for two solutions which is equal to M1V1 = M2V2. (16.4 milliliters of HCl)M1 = (12.7 milliliters) (0.620 M KOH) and you have 0.480M HCl. The answer is number 2.

what are the three molecules that are attached to the plasma membrane, and what are their roles/ functions?

Answers

Answer:

Ans:

*Carbohydrates

*Proteins

*Cholesterol

Explanation:

The plasma membrane is a structure that has several distinct roles in the cell

The plasma membrane is mainly composed of the phospholipid Bilayer, which is a layer of two sheets located in the internal and external parts. The Phospholipids are said to be Amphipathic because they have both properties of Hydrophobic and hydrophilic

*The Carbohydrate Molecules attach to the Plasma Membrane such as to the lipids and Proteins:

when They attach to the Proteins, they are known as glycoproteins, and they help in cell recognition, when they attach to the lipids, they are known as Glycolipids

*Protein Molecules play an important role in transport system such as Carrier Proteins

*Cholesterol Molecules help in balancing the Fluidity of the plasma membrane

The process of boiling a mixture so that one part will evaporate, then cooling or condensing the evaporated liquid, and finally collecting the cooled liquid, is known asa. settling.
b. filtration.
c. distillation.
d. evaporation.

Answers

The answer is C. Distillation. Distillation is a common process for separating liquid mixtures by using the principle of volatility and boiling point. For a liquid mixture with two liquid components A and B, A will have a lower boiling point or higher volatility than B. By boiling the mixture at the boiling point of component A, only component A will evaporate from the mixture. The evaporated gas will then be cooled to condense component A back to a liquid.

The answer would be C. :))
